Undead Development 2

Undead Development 2 is a combat-focused zombie survival game for 1 to 4 players. You scavenge points of interest for weapons and supplies, then fortify locations by dragging furniture and junk into barricades and nailing them in place. Play through a series of biomes in Journey or build and defend a base in Hideout Defense.

Build your barricades

The nailing system lets you attach objects to other objects. Barricades are physics objects: drag a couch across a doorway and nail it down, then the horde must break through to get inside. You can line entrances with knives and bear traps, and research more advanced trap creation. There is no recipe list, so you can try combinations such as nailing a bear trap to a door, a knife to a plank or a blade to a spinning machine.

Journey through the biomes

Journey takes you through a gauntlet of increasingly difficult biomes: forest, swamp and city. Scavenge supplies at random points of interest, find a place to barricade and survive until evacuation takes you to the next biome. Runs feature random loot with rarity tiers, random events and randomly generated map levels. Hardcore death penalties are optional.

Defend your hideout

Evacuating a zone in Journey unlocks it as a hideout. Choose one, fortify it and face wave after wave of enemies, improving your base between waves.

Play together

Online co-op supports 1 to 4 players through Steam. Players can divide the work, with one covering a doorway while another reinforces it, then patch barricades between waves while a teammate stands watch. Desktop and VR players share the same lobby, and progression carries between solo and co-op play.

Research and progression

Research expands the loot pool. The Early Access launch includes over 40 items, and each item you unlock begins appearing in runs. Leveling up unlocks random player skins, while challenges reward skins and trophy weapons.

Additional systems

• Difficulty tiers range from power fantasy to hardcore roguelike, with hardcore death available as a separate switch.
• Strain sends you back through the biomes at a higher difficulty. Enemy health does not scale, so enemies do not become bullet sponges.
• NPCs have their own behaviors and abilities, including elite zombies and bandit crews.
• Dynamic systems include tree cutting, spreading fire and physics damage.
• The interface is minimalist; you interact directly with tools and items in the world.
